Oh well, I still think I got a decent deal, and with it being for a Wheel Horse, and there being a bunch of rabid Wheel Horse collectors in this area, I should be able to turn a wee bit of profit on it.

The Lagrange Engine Club has a pretty big show in Wellington Oh in Aug, and a LOT of GT folks show up, so I might be able to find a sickle bar for the Bolens and 'turn' the 414.

The more I look at it, the more I'm thinking that it just MIGHT work on a tube frame.

I got the 405-A manual from another site, and it looks virtually identical to the 414. It doesn't have that pulley/PTO gearbox, but that, and possibly some mounting brackets may be what made it a 414 vs a 405-A.

I measured the front mounting bracket, and it will fit on the outside of the mounting tabs at the front of the G10.

The only thing that puzzles me now is that piece that is on the right in the post above. That rascal is HEAVY as it has bars welded to the bottom side. Could it possibly be a counter-weight?

Here's a snip of the pic in the 405-A manual, next to what I have. If you ignore the pulley/PTO unit, and take off that bolted on piece on the front of mine, which I'm guessing is an adapter plate that allows it to mount on a WH, and they are identical.

Not only that, but I measured the U shaped plate in the front, and the inside to inside distance almost exactly matches the outside to outside distance of mounting tabs on the front of the G10, with the plate being just a wee bit wider.

I'm betting that the bolted on plate, and the pulley/PTO unit, and some different mounting hardware, are 'adoptions' that turn a 405-A into a 414.

I'll probably have to see what I need to do to get the PTO connected, but that shouldn't be too hard to do.

I'll play around with it more, when I get either the 800 running properly, or the G10 put back together after I get the hydro unit mounting bars fabbed.

Neither of which is happening today, because it's been raining off and on all day, and I have to do all of my work outside since I don't have enough garage space.

I bet, with a bunch of head scratching, and some good old fashion retro work, that thing will be adaptable to your Bolens.
Basically, It looks the same as my 416A which is meant for a JD 120/140/300, or 317. I made it fit my MF14. Just a
bit of bracketry, and a bunch of head scratching.
It looks to be in good shape, so it's worth a shot.

That info I have from Erwin Haban, was in PDF format, so I couldn't download into the manuals, but I emailed them
to Nutndun, and he's going to convert them, and download them in a day or 2. Interesting stuff.
